Item Identification

Title: Green Sea Turtle (North Atlantic DPS)
Publication Date: 1998-09-02

These data represent critical habitat for the green sea turtle (North Atlantic DPS) as designated by Federal Register Vol. 63, No. 46693, September 2, 1998, Rules and Regulations.On April 6, 2016, the National Marine Fisheries Service and the US Fish and Wildlife Service issued a final rule (81 FR 20058) to list 11 DPSs of the green sea turtle (which had previously been listed as the entire species). The final rule stated that the existing 1998 critical habitat designation, i.e., waters surrounding Culebra Island, remains in effect for the North Atlantic DPS of green sea turtle.


The purpose of these data is to visually represent the critical habitat areas for GIS analysis and display.

Access Information

Security Class: Unclassified
Data Use Constraints:

Users be advised that the accuracy of this data set is completely dependent upon the accuracy of the shoreline data used in the creation process. For more details on this process, see the process description. The text description in 63 FR 46701 is always the one, true definition of green turtle critical habitat. These or any other depictions are for information purposes only and shouldn't be relied on for regulatory purposes.

Process Steps

Process Step 1

CC ID: 1082414

Detailed shoreline for Culebra Island from NOAA digital vector chart was appended to add smaller islands, then a 3 nautical mile buffer was generated using ESRI's ArcGIS software

Process Date/Time: 2005-07-12 00:00:00

Process Step 2

CC ID: 1082415

Land area was erased from the buffer area using ET Geowizards. The source of land area used to erase was from the NCCOS project for coral and seafloor mapping.

Process Date/Time: 2005-07-12 00:00:00

Process Step 3

CC ID: 1082416

FR 46699 Vol. 63 No 1700 Sept 2, 1998 was reinterpretted and there is a map in the FR which shows that the islands weren't buffered, only Isla de Culebra. Projected base data to WGS-Mercator (units=meters), and buffered to 5.6 km. This buffer does not look like the FR, as it bisects Cayo Lobito. Then the data was reprojected to GCS-WGS84.
